No such file or directory in experiments/Feb_1_learning_alphabet_corr/1/

I'm using the latest code from master branch.
Running `python experiments/Feb_1_learning_alphabet_corr/1/experiment.py` results in exception:
```
Traceback (most recent call last):

with open(datapath("omniglot_data.pkl")) as f:
IOError: [Errno 2] No such file or directory: '/Users/Sida/repos/hypergrad/data/omniglot/omniglot_data.pkl'
```

I looked into the code and found that on line 15 of `omniglot.py` in function `datapath`, the path is hard-coded as ` datadir = os.path.expanduser('~/repos/hypergrad/data/omniglot')`.
